The quest for longevity has become a multi-billion-dollar industry, with a plethora of products and services promising to slow down the aging process. But what does the science actually say? In this article, we delve into the world of longevity research and explore the advice of experts in the field. We'll uncover the truth behind the hype and the scams, and discover the simple, evidence-based strategies that can help us age gracefully.
The Science of Longevity
The experts at the Longevity Summit in Dublin shared their insights on what actually works to slow down aging. Their message? It's all about lifestyle and simple, evidence-based strategies.
"It starts with lifestyle," says Dr. Matt Kaeberlein. "Eat a high-quality diet, exercise regularly, get good sleep, have some friends, go out and have fun sometimes, manage your stress well." He emphasizes the importance of muscle mass, which is often overlooked.
Eric Verdin, who runs the Buck Institute for Research on Aging, agrees. "Walking 15 minutes every morning and every night. Who cannot do this? That will have a massive impact on your health, way more than any supplement."
Kennedy Schaal, the founder of Rejuve Biotech, takes it a step further. "Sleep is the hack."
Dr. Rozalyn Anderson, an Irish professor at the University of Wisconsin-Madison, offers a simple and relatable approach. "The key indicator is if the jeans start getting tight - you know something’s going on, and it’s time to take action." She emphasizes the importance of balance, suggesting a moderate approach to lifestyle choices.
The Importance of Social Connections
One thing that kept coming up was the importance of social connections. Martin O'Dea, the summit's founder, pointed to a talk on how isolation harms older people. He built a "longevity pub" into a scientific conference, emphasizing the importance of social interaction.
A meta-analysis of 148 studies and over 300,000 people found that those with stronger social ties were about 50% more likely to be alive at follow-up - an effect its authors compared to giving up smoking.
The Risks of IV Drips and Peptides
The experts were quick to point out the risks of IV drips and peptides, which are often promoted as miracle cures. Dr. Kaeberlein warns against the use of peptides, which are often imported from China and Russia and may be contaminated with enterotoxins or other drugs.
Eric Verdin is even more blunt, calling IV infusions of NAD "medical scams in a white coat." He emphasizes the importance of testing and measuring before supplementing.
The Importance of Testing and Measuring
The experts agree that testing and measuring are crucial. Dr. Kaeberlein suggests that if you can measure it in your blood and you're not in the optimal range, it probably makes sense to supplement to get into the optimal range.
Dr. Anderson gives an example of how they weigh each animal in their lab, down to 0.1 of a gram, to decide how much drug to give them. She contrasts this with the unsophisticated approach of taking two pills in the morning and two in the afternoon.
The Future of Longevity Research
The experts are optimistic about the future of longevity research. Dr. Kaeberlein's work on rapamycin, a drug that has shown promise in slowing aging, is an example of the progress being made.
Steve Horvath, who built the first multi-tissue "epigenetic clock" that estimates biological age from a blood sample, is excited about the potential of human clinical trials.
The Unglamorous Truth
Dr. Anderson sums up the unglamorous truth: "Mortality is still at 100%." But she emphasizes that "how we age is not inevitable." She encourages people to take action and make changes to their lifestyle, as there's a good chance it will work.
The experts agree that the simple, evidence-based strategies they recommend are effective and affordable. They warn against the scams and hype, and encourage people to test and measure before supplementing.
In conclusion, the quest for longevity is a complex and ongoing journey. But by listening to the experts and adopting a balanced, evidence-based approach, we can age gracefully and healthily.
